Title: Method for efficient representation and processing of color pixel data in digital pathology images
Inventor: ROBERTSON MARK
IPC: G06T9/00
Filed: 2012-03-22
Abstract: Efficient representation of color digital pathology images (DPI) is described herein, which is accomplished by exploiting properties unique to such images. The method decomposes the data into constituent parts whose relative importance is able to be specified, allowing the data to be accurately represented with less bit precision, less spatial resolution or less spectral resolution. Two specific areas where the method is able to be utilized include: (1) more-efficient image compression; and (2) more efficient processing of the data. Efficient image compression is accomplished by assigning fewer bits to less-important colors. Efficient data processing is accomplished by processing only those colors, or combinations of colors, that are deemed important.

Abstract: A support system negotiates secure connections on behalf of multiple guest systems using a set of credentials associated with the guest systems. The operation of the secure connection may be transparent to the guest system such that guest system may send and receive messages that are encrypted or decrypted by the support system, such as a hypervisor. As the support system is in between the guest system and a destination, the support system may act as a local endpoint to the secure connection. Messages may be altered by the support system to indicate to a guest system which communications were secured. The credentials may be managed by the support system such that the guest system does not require access to the credentials.

Title: Strain-promoted crosslinking of peg-based hydrogels via copper-free cycloaddition
Inventor: WEISS ROBERT A
IPC: C08L63/10
Filed: 2013-07-31
Abstract: The present invention is directed to a covalently crosslinked hydrogel comprising the strain-promoted reaction product of an 8-member cycloalkyne functionalized polyalkylene glycol and a multi-arm glycerol exytholate triazide and methods for making them. Because the precursor materials can be manipulated without causing crosslinking, provided the strain threshold is not reached, these hydrogels permit mechanical control over when (and where) cross linking occurs and are easier to use than prior strain-activated or temperature-activated systems. These novel hydrogels do not require a catalyst to cross link, thus avoiding the biocompatibility problems common to many catalysts. Nor is the crosslinking process affected by the presence of catalysts or other substances, which have interfered with crosslinking in known strain induced hydrogels. Because of their crosslinking reaction kinetics, these novel hydrogels can encapsulate and transport highly sensitive cells and other biological additives and have no known toxic byproducts.
